Taphonomic Analysis

The use of bone as raw material for implements is documented since the Early Pleistocene. Throughout the Early and Middle Pleistocene bone tool shaping was done by percussion flaking, the same technique used for knapping stone artifacts, although bone shaping was rare compared to stone tool flaking. Until recently the generally accepted idea was that early bone technology was essentially immediate and expedient, based on single-stage operations, using available bone fragments of large to medium size animals. Only Upper Paleolithic bone tools would involve several stages of manufacture with clear evidence of primary flaking or breaking of bone to produce the kind of fragments required for different kinds of tools. Our technological and taphonomic analysis of the bone assemblage of Castel di Guido, a Middle Pleistocene site in Italy, now dated by 40Ar/39Ar to about 400 ka, shows that this general idea is inexact. In spite of the fact that the number of bone bifaces at the site had been largely overestimated in previous publications, the number of verified, human-made bone tools is 98. This is the highest number of flaked bone tools made by pre-modern hominids published so far. Moreover the Castel di Guido bone assemblage is characterized by systematic production of standardized blanks (elephant diaphysis fragments) and clear diversity of tool types. Bone smoothers and intermediate pieces prove that some features of Aurignacian technology have roots that go beyond the late Mousterian, back to the Middle Pleistocene. Clearly the Castel di Guido hominids had done the first step in the process of increasing complexity of bone technology. We discuss the reasons why this innovation was not developed. The analysis of the lithic industry is done for comparison with the bone industry.

The l’Hort de la Boquera site is located in the northeastern part of Iberia and its stone tool assemblage includes up to 25,000 flint artefacts. This is the first approach to the analysis of the raw material through an archaeopetrological study. Results were obtained by use of mineralogi¬cal techniques: macroscopic and petrographic analysis, Scanning Electronic Microscopy (SEM), Micro-Raman and X-Ray diffraction (XRD); additionally, Laser Ablation Inductively Coupled Plasma Mass Spectrometry was applied. It has been possible to discriminate at least four flint categories, the ‘Evaporitic flint type’ (with two local subvarieties – ‘Common evaporitic’ and ‘Garnet’ varieties) that comes from local outcrops of the Ulldemolins Complex, and two flint types that had their origin further afield: the ‘Charophyta flint type’ (coming from the Torrente de Cinca Unit) and the ‘Dark flint type’ (from the La Serra Llarga Formation).These results make this study the most comprehensive analysis of raw materials that has been carried out in the area so far

And Behavior

In addition to the functional, anatomical, and paleopathological reflections of the biology and behavior of the Sunghir humans, it has been possible to make indirect inferences regarding their average dietary profiles. These considerations derive from the mineral compositions of bone samples from Sunghir 1 to 4 (Kozlovskaya 2000d), carbon and nitrogen stable isotope data from the bone collagen of Sunghir 1 to 3 (Richards et al. 2001; Dobrovolskaya et al. 2012), and postcanine buccal microwear for Sunghir 1 to 3 (Pinilla 2012; Pinilla and Trinkaus in press). As noted in chapter 2, the site contained an abundance of large mammal remains, of which the bison, horse, saiga, and especially reindeer remains were undoubtedly brought to the site for human consumption. There was also an abundance of mammoth remains. There has been an ongoing debate as to the extent to which the mammoth remains, found at a number of central and eastern European and Siberian Mid Upper Paleolithic (MUP) sites, reflect human consumption, are largely incidental to the human presence having accumulating along the banks of gullies and streams, and/or were gathered from the landscape for use as raw material and even fuel (e.g., Soffer 1985; Derevianko et al. 2000; Svoboda et al. 2005; Wojtal and Wilczyński 2013). Systematic taphonomic analysis of the Sunghir faunal assemblage has not been undertaken, but Bader (1978) did notice the differential presence of mammoth skeletal elements at Sunghir, suggesting differential transport of body portions presumably for human consumption. Moreover, the mammoth bones were distributed through the cultural layer and apparently did not exist as a bone accumulation on the periphery of the site. At the same time, the faunal profile of the cultural layer contained a diversity of carnivores, of which the cave lions, wolves, and possibly brown bears could have been partially responsible for some of the herbivore remains at the site. It is possible that humans were hunting and eating the bears, given occasional cutmarks on bear bones at other MUP sites (Wojtal 2000; Münzel and Conard 2004).

The chapter is devoted to the earliest human settlement in Nubia, which took place in the Pleistocene, with numerous references to neighboring areas, especially Upper Egypt. Paleolithic groups of humans probably appeared in Nubia in the Early Pleistocene, but well-documented sites—connected with Lower Paleolithic-Acheulean complex industries—are dated only to Middle Pleistocene (MIS 9-7). Some of the oldest Middle Stone Age (MSA) assemblages in Africa were discovered in Nubia (ca. 220 ka, MIS 7). Numerous MSA sites (ca. 220–40 ka, MIS 7-3) with predominating Levallois technology are situated within the Nile valley and the neighboring deserts, mainly in oases. The onset of Upper Paleolithic (ca. 40–20 ka, MIS 3-2) blade technology was recorded together with the oldest mining. Late Paleolithic groups of humans (20–11 ka, MIS 2), characterized by considerable diversity in the hyper-arid period, lived only in the Nile valley. Local examples of rock paintings come from that period. Pleistocene human remains from Nubia are extremely rare; they all represent H. sapiens. Cemeteries with numerous burials, some of which display evidence of violence, were also discovered in this area.

Isimila is a Middle Pleistocene archaeological site located in southern Tanzania. The site is known for large surface assemblages of later Acheulean lithics such as hand axes, cleavers, scrapers, and cores. While hominin remains have yet to be discovered at the site, Isimila offers a unique window into Middle Pleistocene Homo behavior. Although Isimila has been studied extensively, the last published map of the site and surrounding area was made available in the 1970s. Here, we present an updated high-resolution map of Isimila. Data for the map were collected during aerial survey with an uncrewed/unmanned aerial vehicle (UAV). With this map, we identify new archaeological localities, erosional patterns, newly exposed geological features, and changes in site topography. The map reveals patterns of stone tool and raw material distribution that may support previous hypotheses of raw material transport into the area by hominins. This open-access map establishes a baseline for tracking changes to site topography in the future and serves as a unique tool to enable collaboration between researchers, museum personnel, and local populations to better conserve Isimila.

Climate Transition

Abstract The interplay between Pleistocene climatic variability and hominin adaptations to diverse terrestrial ecosystems is a key topic in human evolutionary studies. Early and Middle Pleistocene environmental change and its relation to hominin behavioural responses has been a subject of great interest in Africa and Europe, though little information is available for other key regions of the Old World, particularly from Eastern Asia. Here we examine key Early Pleistocene sites of the Nihewan Basin, in high-latitude northern China, dating between ∼1.4 and 1.0 million years ago (Ma). We compare stone-tool assemblages from three Early Pleistocene sites in the Nihewan Basin, including detailed assessment of stone-tool refitting sequences at the ∼1.1-Ma-old site of Cenjiawan. Increased toolmaking skills and technological innovations are evident in the Nihewan Basin at the onset of the Mid-Pleistocene Climate Transition (MPT). Examination of the lithic technology of the Nihewan sites, together with an assessment of other key Palaeolithic sites of China, indicates that toolkits show increasing diversity at the outset of the MPT and in its aftermath. The overall evidence indicates the adaptive flexibility of early hominins to ecosystem changes since the MPT, though regional abandonments are also apparent in high latitudes, likely owing to cold and oscillating environmental conditions. The view presented here sharply contrasts with traditional arguments that stone-tool technologies of China are homogeneous and continuous over the course of the Early Pleistocene.

AbstractThe island of Gran Canaria is regularly affected by dust falls due to its proximity to the Saharan desert. Climatic oscillations may affect the Saharan dust input to the island. Geochemical, mineralogical, and textural analysis was performed on a well-developed and representative early Pleistocene paleosol to examine Saharan dust contribution to Gran Canaria. Significant and variable Saharan dust content was identified in addition to weathering products such as iron oxides and clay minerals. Variations in quartz and iron oxide concentrations in the paleosol likely reflect different Saharan dust input in more/less-contrasted rhexistasic/biostatic climatic conditions. Linking the quartz content in Canarian soils, the Ingenio paleosol, and two Canarian loess-like deposits to different ages from the Quaternary, we hypothesized that the dust input should be lower (about 33–38%) throughout the early to middle Pleistocene than during the late Quaternary. The Saharan dust input to the Gran Canaria profile in the Pleistocene persisted in spite of climatic variations.

<p>Multi-level cave systems record the history of regional river incision in abandoned alluvium-filled phreatic passages which, mimicking fluvial terrace sequences, represent former phases of fluvial base-level stability. In this respect, cosmogenic burial dating of in cave-deposited alluvium (usually via the nuclide pair <sup>26</sup>Al/<sup>10</sup>Be) represents a suitable method to quantify the pace of long-term river incision. Here, we present a dataset of fifteen <sup>26</sup>Al/<sup>10</sup>Be burial ages measured in fluvial pebbles washed into a multi-level cave system developed in Devonian limestone of the uplifted Ardenne massif (eastern Belgium). The large and well-documented Chawresse system is located along the lower Ourthe valley (i.e. the main Ardennian tributary of the Meuse river) and spans altogether an elevation difference exceeding 120 m.</p><p>The depleted <sup>26</sup>Al/<sup>10</sup>Be ratios measured in four individual caves show two main outcomes. Firstly, computed burial ages ranging from ~0.2 to 3.3 Ma allows highlighting an acceleration by almost one order of magnitude of the incision rates during the first half of the Middle Pleistocene (from ~25 to ~160 m/Ma). Secondly, according to the relative elevation above the present-day floodplain of the sampled material in the Manants cave (<35 m), the four internally-consistent Early Pleistocene burial ages highlight an “anomalous” old speleogenesis in the framework of a gradual base-level lowering. They instead point to intra-karsting reworking of the sampled material in the topographically complex Manants cave. This in turn suggests an independent, long-lasting speleogenetic evolution of this specific cave, which differs from the <em>per descensum</em> model of speleogenesis generally acknowledged for the regional multi-level cave systems and their abandoned phreatic galleries. In addition to its classical use for inferring long-term incision rates, cosmogenic burial dating can thus contribute to better understand specific and complex speleogenetic evolution.</p>

Giouchta Mt. is located south of Heraklion city, in Crete. It is an N-S trending morphological asymmetric ridge, with steep western slope whilst the eastern slope represents a smoother relief, composed of Mesozoic limestone and Eocene- lower Oligocene flysch sediments of the Gavrovo -Tripolis zone. The present study focuses on the geological structure of Mt. Giouchta. Field mapping and tectonic analysis is performed for this purpose. The dominant structures are contractional in nature, deformed by normal faulting related to the extensional episodes initiated in Serravallian times. The strain pattern in the area is revealed from strain analysis. It is inferred that the orientation of the stress field in the area has changed several times: the N-S, stress field which was dominant during Late Serravallian times changed to NE-SW (in Late Serravallian? - Early Tortonian) and subsequently to WNW-ESE (Early to Middle Tortonian) to become NW-SE in Late Tortonian. This orientation changed also during the Quaternary times trending from NW-SE (Early Pleistocene) to ENE-WSW (Middle Pleistocene-Holocene). In addition to the above, surface soil samples were collected in the wider area of mount Giouchta and they were analyzed in order to determine the magnetic susceptibility. GIS techniques were used for mapping the spatial distribution of the geological features and the magnetic measurements on the topographic relief of the area. Statistical analysis techniques were also applied in order to investigate the relation of faulting and magnetic susceptibility. Maps representing the spatial distribution of the above measurements were created by using appropriate interpolation algorithms.

For the first time, materials of such settlements of the East Trypillia culture as Trostyanchyk, Onopriyivka І are published. Despite approximately the same quantitative ratio, even at first glance, the materials of these two leaflets differ significantly from each other. The Trostyanchyk complex is actually blade-type: blades prevail both among production waste and among the tool kit. Flakes and tools on them dominate in Onopriyivka. If the Trostyanchyk complex can be regarded as "classic" in terms of the tool kit: retouched blades, end-scrapers, sickle inserts, perforators on blades, etc., then the Onopriyivka complex looks more primitive: retouched flakes, notched tools and scrapers on flakes, and others. In Onopriyivka, unlike Trostyanchyk, finds of weapons are completely absent. Products from Onopriyivka are made mainly of local raw materials, while in Trostyanchyk there are approximately equal parts of products from local and imported raw materials, and products from local flint are made as carefully as products from Volyn flint. At the same time, in both cases we can confidently speak of the local nature of production. This is evidenced by both the use of local flint raw material and the specific items present in both collections. In Trostyanchyk, as already mentioned, a hammerstone was found, in Onopriyivka — core-like fragments and chips of modify of cores. Such differences can be explained by both territorial and chronological discrepancies. Onopriyivka I is earlier, refers to the end of stage ВІ, Trostyanchyk — to the end of stage ВІІ. Trostyanchyk is located on the Southern Bug, Onopriyivka — in the Bugo-Dnieper interfluve. Although, perhaps, this situation is explained by the unevenness of the study of these sites. In addition, materials from the Vladyslavchyk settlement are published for the first time. Based on their analysis, using analogies from related and synchronous sites, the author tried to identify the features of the East Trypillia lithic industry in the Bug-Dnieper rivers interfluve. As it turned out, at the modern level, the identification of such features is not possible. The materials of the East Trypillia culture of the region are, on the whole, more similar to the materials of the settlements of the West Trypillia culture, than to related sites on the Southern Bug.
